1 is formed so as to be located substantially above the respective engagement grooves 11 to 11.

On the upper surface side of the 22-piece cap 20, a fixed cam is screwed to the support shaft 5, and a cam 23 is formed on the upper edge of the outer wall thereof. The cam 23 has a notch 24 formed over a predetermined range, and the cam 23 has a notch 24 extending over a predetermined range.
6, guides the followers 26-26 of each push-in gauge 25-25 to slide with rotation in the direction P (not shown).

Now, in this example inspection and sorting machine 1, in order to judge the quality of Pol) B, regarding the bolt head B2, the hole depth and inner diameter of the wrench insertion hole B3, etc., and further regarding the bolt shaft portion B1, Each element, such as the thread pitch and shaft diameter, is the inspection element.

First, the measuring mechanism regarding the wrench insertion hole B3 of the bolt head B2 will be explained (see FIG. 4).

Each of the push gauges 25 to 25 is inserted into each of the insertion holes 21 to 21 of the cap 20 so as to be able to slide in the vertical direction i1+J. Further, on the lower surface of the follower 26 of each of the push gauges 25 to 25, a hexagonal note-shaped gauge rod 27 that can fit into the insertion hole B5 of the pole B is vertically installed. Notch part 2
4, it is inserted into the insertion hole BS of the B head B1 by the downward movement of the push gauge 25, and the notch 24 hole 41 is separated by the upward movement of the push gauge 25. sell.

A cap nut 28 is screwed to the upper end of the support shaft 5, and a support arm 29 extends from the side thereof.

The direction in which the core support arm 29 extends is set so that it passes above the cutout corner 24 of the fixed cam 22, and a linear gauge sensor 31 is attached to the extending end via a member 30. is installed.

Reference numeral 32 denotes a swinging member which is pivotally attached to the member 30 and swings in the vertical direction around the support bolt 33. Therefore, when the push gauge 25 reaches the test position and the tab notch 24 and the tip end of the swinging member 32 is pushed down by the follower 26, the swinging member 32 will conversely have a weight on the rear side. Linear gauge sensor 3 at 32A
Press 3's spindo/l/34 -F. Then, in the arithmetic processing mechanism, a pass/fail judgment is made based on the raised value of this spindle A/34. That is, spindo 1v34
The push-up force is sent from the linear gauge sensor 31 to the comparator 35, where it is compared with a preset tolerance range, and further, based on this comparison, an operation command can be given to a solenoid 36 for taking out acceptable parts, which will be described later. .

Next, regarding the astronomical measurement mechanism related to the bolt shaft portion B1 ( (See Section 5).

37 is a ring gauge formed in an arc shape;
Below the near gauge sensor 31, a plurality of gauge structures are installed on the outer wall of the parts carrier 10 with a required gap, and on its inner periphery, the gauge structure can be adapted to the thread pitch of the bolt B to be inspected. They are carved in parallel along the same direction.

Further, the ring gauge 37 moves forward and backward in the direction XX' shown in the figure with respect to a base 40 fixed on the base 6 via a holder 39. Although not shown, the holder 3
A spring 9 is inclined inward and biased so as to press the pole B toward the rotating drum 15.

Reference numeral 41 denotes a gauge sensor fixed to the base 6, and the tip of its spindle v42 is in contact with a plate 43 protruding in either direction from the lower part of the holder 39. Then, in the arithmetic processing mechanism described above, a pass/fail determination of Pol I-B is made based on the amount of retreat of the ring gauge 37 (the amount of retreat of the plate 46).

That is, the amount of retreat sent from the gauge sensor 41 is compared with a preset tolerance range in the comparator 44, and an operation command is given to the solenoid 36 for taking out acceptable parts in accordance with this comparison.

The solenoid 36 is attached to the upper part of a column erected on the base 3, and is provided with a hook 46 as an actuator for taking out approved parts. Although the nuclear hook 46 is not shown in detail, the head B2 of the bolt B can be hooked to the bolt B after measurement is completed by a pass signal from the arithmetic processing mechanism, and the bolt B can be flipped outward, while the core hook 46 can be flipped outward by a fail signal. evacuate to a position where it can continue to increase its transparency. In addition,
47 is the 1st V-toe for taking out the accepted bolts that have been kicked out by the hook 46, while 48 is the 2nd V-toe for ejecting the rejected bolts that fall by themselves after being bitten by the hook 46. be. Further, from the introduction V NEET 4 to the second V5-TO 48, bolts B are provided along the outer wall of the parts carrier 10 on the outside of the parts carrier 10 except for the ring gauge 37 and the outlet for passing bolts.
A falling-off prevention wall 50 is installed at a predetermined gap to prevent the falling off of the wall.

Next, the functions and effects of this example configured as described above will be explained in detail.

When a drive source (not disclosed) is driven, the rotation support cylinder 6 is rotated via the drive gear 9 and the driven gear 8. As a result, the cam plate 12, parts carrier 10 and cap 2
0 are rotated in the same direction at the same speed. On the other hand, since the drive pulley 18 is also rotated by the driving of the drive source, the timing belt pulley 17 is rotated via the timing belt 19, and thereby the rotating drum 15 is rotated. However, as described above, the rotating drum 15 is rotated at approximately twice the speed of each of the cam play 12, parts carrier 10, and cap 20.

Under such a situation, the poll) B to be inspected is poured from the introduction V NEET 4 and is sequentially engaged in each of the engagements tlf11 to tlf11 of the parts carrier 10. In this case, due to the inclination of the base 3, the parts carrier 10 is inserted into the part carrier 10 according to a predetermined principle with respect to the horizontal plane, so as the parts carrier 10 rotates, the introduced parts 4 and each engagement When the four IfIts 11 to 11 are inserted, each bolt B is smoothly engaged in the engagement groove 11 one after another due to its own weight.

When the part B received in the parts carrier 10 is carried to the safe position in this manner, each of the above-mentioned parts (★ capital) is removed.

First, the inspection regarding the bolt shaft portion B1 will be explained.

When the inspection-safe bolt B enters the ring gauge 37, the nuclear bolt B passes through this gap, and the ring gauge 37
, pushing the holder 39 outward. The pushed amount at this time is determined by the gauge sensor 41 via the plate 43.
Detected at The detection result is judged as pass/fail based on the comparison with the tolerance range predetermined in the funparator 44, and the hook of the extraction solenoid 46 is set according to the judgment output perform the operation.

That is, the hook 46 connects the detected value and the insertion hole B3.
Detection of [If both are within the allowable range, after passing the ring gauge 37, pol) +? 1i part B2
1 is ejected from all B2 digits to the first chute 47, and conversely, if the thread pitch of bolt B does not match the gauge groove 58 of the ring gauge 37, or if the @ diameter is outside the allowable cylinder size. then retreats to a position where the nucleus Pol)B can pass through.

Now, in the song in which Pol) B advances on the ring gauge 37, rotation is performed according to the opening clock. This is parts carrier 1
This is caused by the difference in rotational speed between the rotary driver 7-15 and the rotational speed of the rotary driver 7-15. Therefore, the above-mentioned inspection regarding the bolt shaft portion B1 is performed over the entire shaft portion B1, so that the thread pitch can be checked over the entire area. It is also possible to accurately inspect for warpage, etc.).

Next, the inspection regarding the insertion hole B3 of the port head B2 will be explained. This inspection is performed at approximately the same time as one moxibustion test regarding the shaft portion B1.

While the cap 20 is rotated, each push gauge 25 rotates around the rotation cam 22 and at the same time each follower 26
When the cam slides on the cam 23, the mechanical force generated therebetween causes it to rotate around the opening shown in the figure.

When the push gauge 25 of fE'R reaches the notch 24 of the cam surface 26, the push gauge 25 descends under its own weight, and the ring gauge 37
A gauge rod 27 is inserted into the inlay B3. At this time, as mentioned above, Pol) B is rotating in the direction of gravity when shown, and conversely, as mentioned above, the push gauge 25 is 1+
21 and 11 are rounded counterclockwise, game! /vt
t2y and insertion hole B3 are instantaneously engaged.

Thus, when the gauge 127 is inserted into the insertion hole B3,
The seven orifices 26 actuate the swinging member 32 in response to this insertion. Then, the weight part 32 of P@ moving member 32 1
The straight-up turtle A is ejected by the linear gauge sensor 31. In the arithmetic processing mechanism, the nuclear detection chisel is judged to be pass/fail based on a comparison with an allowable range preset in the comparator 35, and an operation command is given to the extraction hook 46 in accordance with the judgment output. That is, if this test and the above-described test regarding the shaft portion B1 both pass, the seven-piece 46 performs the ejecting operation to the first chute 47 as described above, and conversely, if this test fails, e.g. If the insertion hole B3 is not formed or if the hole depth is outside the allowable cylinder depth, the retracting operation is performed.

As described above, if the selection of pol-B is made at the measurement position, the accepted bolts B are discharged to the first chute 47, and the rejected bolts pl-B are transported as they are by the parts carrier 10, and the falling-off prevention wall 50 After passing through the second chute 48
It is taken out by falling naturally. Further, the timing of sorting and determining the polls B that are sequentially sent to the measurement position is performed in synchronization with the timing when each of the light shielding blades 13 to 16 passes over the light projecting element 14.

Although the present invention has been shown and described with reference to preferred embodiments, various modifications may be made without departing from the spirit of the invention, and the present invention is not necessarily limited to the form set forth herein. It's not a tortoise.

For example, instead of the wall 50 as the shoulder drop prevention 1, or the fall prevention wall 5
0 and an oil sensor pace, and in addition to the inspection elements of this example (screw surface, bolt height, insertion hole depth, distance between two sides, etc.), other inspection elements are added to expand the application range of inspection. It is possible to expand the book.

Also, contrary to this example, it is also possible to discharge the rejected bolts to the 1st g', -) 47 and the accepted bolts to the 2nd sz, -) 48, and furthermore, take out the rejected bolts for each inspection element. It is also possible to make it straight, and in this case, defective elements can be removed. Furthermore,
The parts to be inspected are not limited to the six-socket bolt as in this example, but may also be other parts; in this case, the ring gauge 37 and the gauge! 'li@27 is replaced with other gauge means.

As described above, the present invention can automatically check the quality of parts.
It is a cross-inspection sea bream betsuki that separates the illumination, and includes a parts conveyance operation section that imparts autorotation and circumferential rotation to the parts that are first carried in from the introduction path, and an inspection disposed around the conveyance operation section. The gist is that the device is equipped with a device.

According to the present invention, with this configuration, it is possible to automatically select the quality of the shivers. In particular, since the transportation of parts involves rotation and rotation at the same time as mentioned above, it is possible to check the parts all around the circumference, thus making the inspection more reliable. .

As described above, the present invention is extremely useful for this tester and is desired by the industry.
